background_colour

This variable can be changed to change the
current room's background colour.

Syntax:

background_colour

Returns: Real

Description

When in a room, it can have no background image selected for any
of its background_index, in which
case you should set a background colour with this variable and make
sure that the background_showcolour
variable is set to true so it can be seen. Having a room
with no background image and no background colour will
result in graphical artefacts being drawn on the screen and is not
recommended.
